Question

In a traverse survey, the closing error means

• A. None of the above
• B. The actual distance by which the traverse fails to close
• C. The distance between the starting and end point of an open traverse
• D. The error in closing of the traversing operations

Answer 1

The correct option is B The actual distance by which the traverse fails to close

Closing error is the distance by which the end of the traverse falls short in coinciding with the starting point of the traverse.

$Closingerror\left(e\right)=\sqrt{(\sum L{)}^2+(\sum D{)}^2}$

Remember

$where\sum L=algebricsumofthelatitudes=e_y$

$\sum D=algebricsumofthedepartures=e_x$

The direction of the closing error.

$tan\theta =\frac{\sum D}{\sum L}=\frac{e_x}{e_y}$

Remember
